| Nowadays,the Internet has become a necessity for people to produce and live.Like water and electricity,the network is the foundation of social operation.With the rapid development of science and technology,network has become a catalyst to promote the development of science and technology.The increase of network users leads to the increasing demand for network bandwidth.In the case of large-scale impact on network traffic caused by the rise of P2 P,how to ensure network bandwidth and maintain network information security is facing great challenges.However,such problems cannot be improved by increasing bandwidth and upgrading network.Therefore,we need to use deep packet inspection(DPI)technology to build a network system which is convenient for operation,monitoring and management to meet the development of the times and the needs of users.Based on the actual network situation of Xinjiang mobile,this paper uses the DPI technology to construct the networking scheme.It realizes effective network traffic information and trend identification and analysis.It provides a reliable guarantee for the network quality and security control of Xinjiang mobile.This paper first introduces the research background and significance of the project.It analyzes the prospect and significance of DPI development.On this basis,the classification of DPI technology and the types of networking methods are studied.It describes the basic principle and influencing factors of DPI.It takes Urumqi mobile traffic monitoring demand as the background,studies the overall deployment scheme of DPI.Combined with the actual needs of the project,the interface of each functional module,equipment configuration and use are analyzed and elaborated.It focuses on the DPI system for HTTP protocol,360 applications and BT application recognition principle.Based on the actual project of Xinjiang mobile,this paper analyzes the specific establishment and implementation of DPI in detail.On the basis of analyzing the demand of user network service,it designs the networking scheme based on DPI technology.According to the needs of users,it plans the data broadband,calculates the configuration of DPI equipment,ISP information security,traffic blocking and intelligent traffic distribution.It studies the software deployment scheme and gives the software deployment tables of different units.It completes the design of hardware composition and software correspondence.It describes the extension of DPI equipment in business card,equipment software and so on.It focuses on the overall technical architecture of the system,analysis of policy management and synchronization process,data acquisition and transmission process,data acquisition and interface layer design.It discusses the construction of Urumqi mobile communication supplementary network and Gateway project,which improves the access of mobile communication and makes DPI data source more perfect.Through the actual test,it can be seen that the proportion of monthly traffic business and the ranking of users using traffic service direction can support the new business functions required by users,and the actual operation effect is good.The successful implementation of the scheme effectively improves the quality of Xinjiang Mobile’s network management and control,provides users with the quality of Internet access,and provides effective data for the introduction of Xinjiang Mobile’s customer resources.This project will become the design reference of other similar projects,and has a high template demonstration effect. |
